Is it possible to perform a DFU using UART with the new SDK12?

Secure Serial DFU will be added as experimental in the upcoming production release of SDK v13.0.0.

Sorry I accidentially turned this comment into an answer..

@bjorn-spockeli What is the status for HCI DFU for today?

@bjorn-spockeli Thanks for your answer. Good to known that this is a "temporary" issue ;)

@metch (Christopher) : Yes, I agree that in some cases it is better to use the serial bootloader instead of the Over-the-Air BLE bootloader. Support for serial DFU has been removed from SDK v12 becasue the entire bootloader library needed to be rewritten in order to support Secure DFU and we prioritized the BLE transport layer for the SDK v12.0.0 release. We plan to add the serial transport layer in a future SDK release.

I am using a custom dongle based on a nRF51 IC on a PC. The DFU is so much simple and faster over HCI. In some cases, the HCI DFU make sense and is more appropriate than performing the update over the air...

@bjorn-spockeli The UART/HCI bootloader example has been removed in SDK12, and there is no information about this in the SDK release notes... Moreover, the Device Firmware Update over a serial is disabled in the current version of nrfutil. Why this ? Could you elaborate a bit more ?

I think you should be ok if you make sure that the SDK v11 bootloader is compiled against the same SoftDevice header as the application built in SDK v12.

Simplest answer is to try. Don't expect much tough. Features are removed from SDK for a reason.

OK, but do you know if it is compatible to use SDK11 bootloader with SDK12 application?

BLE is the only supported transport layer in SDK12 bootloader example: infocenter.nordicsemi.com/.../lib_dfu_transport.html
